This example shows a stylized cat smiley face built as a static SVG graphic using React and D3 v7. It renders a circular face with eyes, eyebrows, whiskers, ears, and a curved mouth, all positioned relative to a central coordinate system. The code defines several D3 arc generators—`arc` for the mouth, and custom `eyeArc` and `earArc` paths—to create the curved shapes, while circles and lines handle the facial features. The entire composition is drawn inside an `<svg>` element within a React component, with hardcoded dimensions and styling.
